Exclusive, patented ruby-orifice nozzles
Cold Fog® systems use our exclusive, patented ruby-orifice nozzles for creating extremely fine water particles droplets, 1-15 microns, that create very little pressure drop and can be designed to humidify & cool to the theoretical limit. Once placed in service, the fog system automatically regulates water-flow based temperature/humidity signals.
Brass or ordinary stainless steel drilled-orifice nozzles have a relative life, since the passage of water under high pressure will easily enlarge the orifice in a short period of use. Nozzle wear is characterized by an increase in nozzle flow, followed by a general deterioration of the spray pattern, increased droplet size and loss of system efficiency. Cold Fog® ruby-orifice nozzles have a 20 year Unconditional Orifice-Wear Warranty. Useful service life is 35 years.

Why Ruby-Orifice Nozzles
Brass or ordinary stainless steel drilled-orifice nozzles have a relative life, since the passage of water under high pressure will easily enlarge the orifice in a short period of use. Nozzle wear is characterized by an increase in nozzle flow, followed by a general deterioration of the spray pattern, increased droplet size and loss of system efficiency. Cold Fog ® ruby-orifice nozzles have Lifetime Unconditional Orifice-Wear Warranty.

“Our misting system has been performing flawlessly since its installation in our Costa Rica biome 15 years ago. It is a critical-path component for the environment’s plants and animals.
It was such a pleasure to speak with Atomizing Systems engineers today and realize how proud they are of the quality of their designs.”
